Over the years you may have followed the progress of ProMusicDB, a rights-management tool and resource that was designed to , among other things, help musicians register their involvement with specific performances and recordings. The project has the potential to generate identifiers that would give music catalogers and archivists very specific ways to distinguish recordings to the track and take level. It also allows musicians to self-register and has the potential to become a resource as a way to identify musicians who might not have had the profile to have been set up in one of the larger authority files.Because of its potential several in MLA and the Encoding Standards Subcommittee have taken a special interest its development.

ProMusicDB, like many other start-ups efforts, has taken some time to mature, but I'm happy to share a report from Christy Crowl at the link below that announces the milestone that they have begun accepting registrations, and summarizes some other work underway.

The Music Library Association is the
professional association for music
libraries and librarianship in the United
States. Founded in 1931, it has an
international membership of librarians,
musicians, scholars, educators, and
members of the book and music trades.
Complementing the Association’s national
and international activities are eleven
regional chapters that carry out its
programs on the local level.
